Summary of OPERATED WASHING MACHINE CONTROL CIRCUIT WITH ATMEGA32
This project features an ATmega32 microcontroller-based washing machine control circuit that precisely manages motor speed, direction, and other functions. The microcontroller uses triacs controlled via opto-isolators (MOC3043 and MOC3023) to adjust 230V motor voltage and maintain a constant drum speed by measuring feedback from a tachogenerator. Additional components control the pump, valves, and heater. The low-voltage control circuitry is isolated from the high-voltage mains. The system can be operated remotely through an IR TV remote, enhancing user convenience.
Parts used in the Washing Machine Control Circuit:
- ATmega32 microcontroller
- MOC3043 opto-triac (zero crossing detector)
- MOC3023 opto-triac (instantaneous response, zero crossing)
- 230V triacs for motor and pump control

WASHING MACHINE CIRCUIT
The rotational speed of the motor is controlled by the microcontroller. Its supply voltage 230V is cut by a triac controlled by the ATmega. Indeed, directly powered by 230V motor rotates the spin speed. It should therefore be slow for washing. But the speed control is rendered necessary because the torque varies alot during each revolution of the drum of the distribution and movement of the laundry in the drum. Hence the presence of the tachogenerator of the motor shaft. the ATmega continuously measures the actual speed of the drum (by a function programmed frequency) and compares it with a setpoint. The result is used to adjust the angle of the triac to maintain constant speed (speed control). This is one of the finer points of the program.
The direction of rotation of the motor is selected by switching the connection of the stator relative to the rotor by two relays. The pump and valves are controlled by triacs. The heater is controlled by a relay 230V – 10A.
The microcontroller circuits and low voltage (5V) are isolated from the 230V mains:
feeding a transformer 230V – 2X6V
triacs by opto-triacs detecting zero crossing MOC3043.
cutting the triac motor voltage by an opto-triac NO detecting zero crossing MOC3023 (instantaneous response)
Everything is managed remotely by a remote control for TV! (it avoids touching anything during operation of the machine)
